What is Computer Vision Syndrome? - A Detailed Guide for Indians

Computer Vision Syndrome (CVS) refers to a range of vision problems arising from prolonged use of digital screens. CVS has become prevalent in India, with the increased usage of digital gadgets for work, study, and entertainment. Symptoms include eye discomfort, headaches, blurred vision, and neck and shoulder pain. Understanding what CVS is and how it impacts your eyes can help you take steps to maintain a healthy vision.

Computer Vision Syndrome Causes

Computer Vision Syndrome has become a highly common issue in the modern world. Some key causes include:

  • Extended Screen Time: Prolonged periods spent staring at digital screens force your eyes to focus and refocus constantly, leading to digital eye strain.
  • Poor Lighting: Low lighting in the workspace or glare from the screen can contribute to eye discomfort and strain. This is also one of the reasons for digital eye strain.
  • Poor Ergonomics: Incorrect distance from the screen can lead to poor posture and cause additional strain on your eyes.
  • Uncorrected Vision Problems: If you have undiagnosed or uncorrected vision issues like farsightedness, nearsightedness, or astigmatism, you may experience more severe symptoms of CVS.
  • Lack of Blinking: When concentrating on a screen, people tend to blink less, leading to dry eyes, which exacerbates discomfort and strain.

Symptoms of Computer Vision Syndrome

The symptoms of Computer Vision Syndrome vary from person to person. However, common symptoms are:

  • Digital Eye Strain: A constant feeling of discomfort or tiredness in the eyes after prolonged screen time.
  • Headaches: Frequent or persistent headaches, especially after long periods of focusing on digital devices.
  • Blurred Vision: Difficulty seeing objects clearly, both on and off-screen.
  • Dry Eyes: A lack of sufficient moisture in the eyes due to reduced blinking, leading to irritation or a gritty sensation.
  • Neck and Shoulder Pain: Poor posture and improper screen positioning can cause strain in the neck, shoulders, and back.

Diagnosis of CVS

Diagnosis of Computer Vision Syndrome typically involves a comprehensive eye examination performed by an eye care professional. This exam may include tests to assess visual acuity and the ability to focus and may involve specific questions about screen usage habits. An evaluation of the patient’s work environment and posture can also help diagnose CVS. By understanding your digital device usage patterns and checking for any underlying vision issues, a doctor can accurately diagnose CVS and provide appropriate recommendations for treatment.

Treatment of Computer Vision Syndrome

Treatment of computer vision syndrome usually requires a multi-faceted approach to alleviate symptoms and prevent further eye strain. Here are some effective treatment methods:

  • Adjust Your Screen Settings: Ensure that the brightness of your screen matches the surrounding lighting. You can also increase the text size to reduce strain on the eyes.
  • Follow the 20-20-20 Practise: Every 20 minutes, take a 20-second break to look at something 20 feet away. This simple practice gives your eyes a much-needed break from the screen.
  • Improve Lighting Conditions: Avoid glare from windows or overhead lights by positioning your screen at a right angle to the light source, and consider using an anti-glare screen filter.
  • Proper Posture and Viewing Distance: Sit about an arm’s length away from your computer screen, and position the screen slightly below eye level to avoid tilting your head.
  • Use Artificial Tears: If dry eyes are an issue, using over-the-counter lubricating eye drops can help alleviate discomfort.

 

In severe cases, an eye care professional may recommend prescription eyewear designed specifically for computer use, which can help reduce eye strain during longer screen times.

How to Prevent Computer Vision Syndrome in Children?

Children are particularly vulnerable to Computer Vision Syndrome due to their increasing screen time for educational and entertainment purposes. The symptoms can be similar to those in adults, but children may not always communicate their discomfort. Parents need to monitor their child’s screen habits and watch for signs such as frequent eye rubbing, squinting, or complaints of headaches.

To reduce the risk of CVS in children, parents can follow these guidelines:

  • Limit Screen Time: Set appropriate limits on daily screen time, particularly for younger children.
  • Encourage Frequent Breaks: Ensure children follow the 20-20-20 rule to rest their eyes regularly.
  • Adjust Screen Setup: Ensure the child’s screen is positioned at the correct height and distance to avoid unnecessary strain.
  • Schedule Regular Eye Exams: Ensure your child receives regular eye exams to detect and address vision issues early on.

 

Proactively managing your child’s screen usage can help prevent or alleviate the symptoms of CVS, ensuring their eye health is protected.

Eye Exercises to Relieve Digital Eye Strain

Incorporating simple eye exercises into your daily routine can help alleviate digital eye strain. These exercises are easy to perform and can be done in just a few minutes:

  • Blinking Exercise: Blink deliberately every few seconds to rehydrate your eyes and reduce dryness. Blinking frequently helps restore the moisture balance in the eyes.
  • Focus Change Exercise: Stretch your hand so the thumb is about 10 inches away from your face. Now, focus on it. Next, shift the focus to an object that is 20 feet away. Repeat this back-and-forth exercise 10-15 times. This will increase your eye focus over time.
  • Eye Rolling Exercise: Close your eyes and roll them slowly in a circular motion. If you do this for 10 seconds, it will relax the eye muscles and relieve strain.
  • Palming Exercise: Rub your palms for warmth and gently place your palms over closed eyes. Hold this position for 30 seconds to a minute to give your eyes a relaxing break.

 

Performing these exercises regularly, especially during long periods of screen use, can reduce digital eye strain and improve overall eye health.

By following these suggestions, you can take control of your eye health and reduce the impact of Computer Vision Syndrome on your daily life.
